Prerequisites
- Vectorial analysis (vectors, scalar and vector fields, differential operators: gradient, rotor, divergency, laplacian)
- Fundamentals of electromagnetism (Coulomb's law, Ampere's law, Gauss Theorem, propagation of electromagnetic waves in transmission lines and in vacuum)
- Fundamentals of circuit analysis
Objectives and Contextualisation
The objective of this course is to form students from the Telecomunications degree in the models and methods frequently used in the field of electromagnetic compatibility (EMC). To this aim, the basic formulations used for the description of interference phenomena and electromagnetic compatibility will be presented. We will also study the national and international directives currently active. We will explore the interference sources and how they are measured using professional instruments.
Competences
- Apply the necessary legislation in the exercise of the telecommunications engineer's profession and use the compulsory specifications, regulations and standards
- Communication
- Conceive, design, implement and operate electronic instrumentation and control equipment and systems.
- Develop ethics and professionalism.
- Develop personal attitude.
- Develop personal work habits.
- Develop thinking habits.
- Learn new methods and technologies, building on basic technological knowledge, to be able to adapt to new situations.
- Manage activities involved in projects in the field of telecommunications.
- Work in a multidisciplinary group and in a multilingual environment, and communicate, both in writing and orally, knowledge, procedures, results and ideas related with telecommunications and electronics
- Work in a team.
Learning Outcomes
- Analyse and specify the fundamental parameters of a communications system, in terms of instrumentation.
- Analyse and troubleshoot electromagnetic interference and compatibility.

Along the course, the students will have to present activities (analysis of papers, readings, etc) assigned by the professor related to the Unity under study. The students will carry out some simulation practices about the subject discussed in the theory classes. The students must also present one subjected related to EMC in agreement with the professor's directives. The course ends with an individual evaluation about the contents of the course.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.
